  • Patent number: 7014141
    Abstract: An unmanned airborne reconnaissance system, the unmanned airborne reconnaissance system including a lightweight, portable, powered aircraft and a foldable launch rail, the aircraft, in a broken down condition and the launch rail in a broken down condition fitable inside a box, the box capable of being carried by one man. The launch system includes an elongated launch rail with the carriage assembly, and a propulsion means for accelerating the carriage assembly from one end of the launch rail to the other. The carriage assembly releasably engages the aircraft so as to propel the aircraft from one end of the launch rail to the other. The propulsion may be by a cartridge that explodes and releases a gas through a cylinder, or by elastic cords. The aircraft is guided through the air either by a programmed onboard computer which controls the control surfaces of the aircraft and/or by remote control. The aircraft typically contains a camera for recording and transmitting images received from the ground below.

  • Patent number: 6995688
    Abstract: Apparatus and method are provided for detecting and responding to aircraft emergencies and, in particular, thwarting attempts to hijack an aircraft including the storage in aircraft computer memory of a pattern of aircraft flight characteristics assumed to be unique to aircraft controlled by hijackers. The invention also periodically detects real-time flight characteristics from the aircraft automatic sensing apparatus and compares the real-time flight characteristics with the stored patterns of assumed aircraft flight characteristics of a hijacked aircraft. The assumed aircraft flight characteristics includes thresholds such as exceeding given airspeeds or altitudes less than a specific altitude. If an assumed stored pattern is matched by the real-time flight characteristics, automatic control is taken of the autopilot, attempts to manually control the aircraft are overridden and the aircraft is caused to automatically begin flying in an emergency holding pattern.

  • Patent number: 6908061
    Abstract: An airship system according to the invention has an airship (110), a base station (120), and at least three measurement points. The airship (110) emits ultrasonic waves upon receiving an instruction from the base station (120). Measurement point units (S1-S3) receive the ultrasonic waves, and thereby measure distances from the airship (110) to the respective measurement points. An MPU that is incorporated in the base station (120) calculates a position of the airship (110). The base station (120) controls a route of the airship (110) based on the calculated position by sending a flight instruction to the airship (110). In this manner, an airship system can be provided that makes it unnecessary for an operator to pilot the airship and that can reduce the load weight and the power consumption of the airship.

  • Patent number: 6898492
    Abstract: A flight recorder designed for small aircraft captures various onboard flight data in real-time and stores it in non-volatile memory. Recorded data includes aircraft's instantaneous position, altitude, attitude, engine RPM, G forces, flap position, cockpit voice and others. These data are obtained from various sensors which are integrated into the recorder. At the end of a flight the recorded data is downloaded into a computer using a wireless communications data transceiver also integrated into the recorder. It does not require removal or attaching any equipment to be able to download data. In addition to accident investigation, applications include training, preventive maintenance and asset monitoring.

  • Patent number: 6847865
    Abstract: A miniature, unmanned aircraft for acquiring and/or transmitting data, capable of automatically maintaining desired airframe stability while operating by remote directional commands. The aircraft comprises a fuselage and a wing, a piston engine and propeller, a fuel supply, at least one data sensor and/or radio transceiver, a microprocessor disposed to manage flight, a radio transceiver for receiving remotely generated flight direction commands, a GPS receiver, a plurality of control surfaces and associated servomechanisms, for controlling flight stabilization and direction, roll, pitch, yaw, velocity, and altitude sensors. The microprocessor uses roll, pitch, yaw, and altitude data to control attitude and altitude of the aircraft automatically, but controls flight direction solely based on external commands. The aircraft does not exceed fifty-five pounds.

    Abstract: A search robot system first divides the entire area of disaster into a mesh cell of an appropriate size, and arranges a search robot for each mesh cell. A search is made for a route of travel from an outermost mesh cell to a casualty and to an adjacent mesh cell. The search robot immediately communicates with a mother robot when a casualty is found. The search robot also communicates with the mother robot when a route to an adjacent mesh cell is found. In the search robot system, a new search robot is arranged to search in an adjacent mesh cell. Accordingly, a rescue activity that is a matter of time can be carried out by a plurality of robots.

  • Patent number: 6735501
    Abstract: A satellite command system and method that provides satellite commanding using remotely-controlled modulation of telemetry parameters on-board a satellite. Software is provided on each of the redundant processor units that creates separate DMA command input pathways to the redundant processor units. A command translator is used at a ground station to translate a command that is to be implemented on the satellite into a form ready for modulation. The command information is uplinked to the satellite by remotely manipulating (modulating) a quantity that can be measured by the on-board computer using its telemetry collection functions. The software implemented in processor units recognizes the modulation and processes it to reconstruct the command. The reconstructed command is passed to the processor unit, which then executes the command.

  • Patent number: 6694228
    Abstract: A control system for a UAV includes control translations which maximize operational employment of the UAV payload. By determining spatial references, and then using the references to transform the control stick commands, the operator treats the UAV as a point source. For control through imagery from onboard mission sensors, the transformations provide for the UAV to move itself and achieve payload orientation.
